In addition, in the nozzle unit 470 of present embodiment, be provided with nozzle and clean chamber 478.Nozzle is cleaned chamber 478 and is fixed on erecting bed 475, by spraying sterilized water or water from being arranged at its inner water-discharge portion 479, can the outer surface of nozzle 473 (housing) be carried out sterilization or be cleaned.That is, switching on while generating sterilized water to the positive plate 451 of electrolyzer unit 450 and minus plate 452 by control part 405, the housing of nozzle 473 by the sterilized water spraying from water-discharge portion 479 by sterilization.On the other hand, in the time that control part 405 is not switched on to the positive plate 451 of electrolyzer unit 450 and minus plate 452, the housing of nozzle 473 is cleaned by physics by the water spraying from water-discharge portion 479.So, the hygienic washing device 100 that present embodiment relates to, can carry out and utilize sterilized water to carry out the sterilization process of sterilization to nozzle 473 and utilize water to carry out clean physics to nozzle 473 and clean operation.
More specifically, be accommodated under the state in shell 400 at nozzle 473, guttation mouth 474 parts of nozzle 473 are incorporated in substantially nozzle and clean in chamber 478.Therefore, nozzle is cleaned chamber 478 can spray sterilized water or water by the water-discharge portion 479 from the portion of setting within it, thereby guttation mouth 474 parts of the nozzle 473 in receiving state are carried out sterilization or cleaned.And, nozzle clean chamber 478 can by the time that nozzle 473 is advanced and retreat from water-discharge portion 479 injection waters or sterilized water, thereby not only to guttation mouth 474 parts, also to the outer surface of other parts carry out sterilization or clean.
In addition, the nozzle 473 of present embodiment is accommodated under the state in shell 400 at nozzle 473, can be by the guttation mouth 474 self having from nozzle 473 spue sterilized water or water, thus guttation mouth 474 parts are carried out sterilization or cleaned.And, be accommodated under the state in shell 400 at nozzle 473, because being incorporated in nozzle substantially, guttation mouth 474 parts of nozzle 473 clean in chamber 478, so the sterilized water spuing from the guttation mouth 474 of nozzle 473 or water are cleaned the inwall reflection of chamber 478 and splashed guttation mouth 474 parts by nozzle.Therefore, guttation mouth 474 parts of nozzle 473 can also be by be cleaned the sterilized water of inwall reflection of chamber 478 or water by nozzle by sterilization or clean.
At this, well nozzle 473 is carried out to sterilization for efficiency, be more preferably the hypochlorous concentration generating in electrolyzer unit 450 higher.And, by more improving the hypochlorous concentration generating in electrolyzer unit 450, can allow the clean feel that user produces nozzle 473 improve.Now, if more reduce the flow of the water of supplying with to electrolyzer unit 450, can more improve the hypochlorous concentration generating in electrolyzer unit 450.
But if more improve the hypochlorous concentration generating in electrolyzer unit 450 for efficiency well nozzle 473 is carried out to sterilization, the flow of water (flow) of utilizing water to carry out in the clean operation of clean physics nozzle 473 likely occurs not enough.,, if reduce the flow of the water supplied with to electrolyzer unit 450, although can improve hypochlorous concentration, on the other hand, likely there is deficiency for the flow of the clean operation of physics of removing the sewage that is attached on nozzle 473, dirt.
To this, the hygienic washing device 100 that present embodiment relates to as previously mentioned, can be carried out and utilizes sterilized water to carry out the sterilization process of sterilization to nozzle 473 and utilize water to carry out clean physics to nozzle 473 and clean operation.And hygienic washing device 100 can be in the case of carrying out sterilization process in the situation that and carrying out physics and clean and make to result from the condition of hypochlorous concentration different operation.The temperature of the water when temperature of sterilized water when more specifically, hygienic washing device 100 can make to carry out sterilization process is cleaned operation from execution physics is different.Or the water yield of supplying with to electrolyzer unit 450 when the water yield of supplying with to electrolyzer unit 450 when hygienic washing device 100 can make to carry out sterilization process is cleaned operation from execution physics is different.Or the advance and retreat speed of the nozzle 473 when the advance and retreat speed of the nozzle 473 when hygienic washing device 100 can make to carry out sterilization process is cleaned operation from execution physics is different.
Thus, can in the situation that carrying out sterilization process, make hypochlorous concentration different from carrying out the clean operation of physics, can efficiency carry out sterilization to nozzle 473 well.And, by more improving the hypochlorous concentration generating in electrolyzer unit 450, can allow the clean feel that user produces nozzle 473 improve.Below, with reference to accompanying drawing, these actions are described.
In addition, in the explanation about Fig. 3～Fig. 5, generate although exemplified electrolyzer unit 450 situation that comprises hypochlorous solution and be used as sterilized water, the sterilized water generating in electrolyzer unit 450 is not limited to this.The sterilized water generating in electrolyzer unit 450 can be also for example the solution that comprises the metal ion such as silver ion or copper ion.Or the sterilized water generating in electrolyzer unit 450 can be also the solution that comprises electrolytic chlorine, ozone etc.Or the sterilized water generating in electrolyzer unit 450 can be also acid water or alkaline water.Even in these cases, as long as comprise feature of the present invention, just comprise within the scope of the invention.Below, for convenience of explanation, take sterilized water as the situation that comprises hypochlorous solution as example describes.
In addition, electrolyzer unit 450 also can not be arranged on stream 20 midway, and be arranged on from watering 10 as the use of electrolyzer unit 450 and the not shown stream of branch midway.Now, also can form the stream of the water-discharge portion from electrolyzer unit 450 to the direct guttation of housing section to nozzle 473.By formation like this, owing to can storing electrolyte, so can be according to the moment of the sterilization sterilized water that in time, effectively spues.In addition, sterilized water supply part is not limited to has electrolytic cell, as long as the parts of sterilized water can be provided.
Fig. 6 represents the action of hygienic washing device that present embodiment relates to and the conceptual schema figure of the summary of stream state.
First, in the time that seat formula inductive pick-up 404 senses the user who is sitting on toilet seat 200 (moment t1), 405 of control parts are opened electromagnetic valve 431, carry out " draining " (moment t1～t2).Thus, the cold water in stream 20 is discharged from, and carries out warm water preparation.Now, control part 405 is not switched on to electrolyzer unit 450, does not generate sterilized water.In addition, the time of implementation of " draining " was for example about about 6～15 seconds.
Next,, in the time that user presses not shown " buttocks is cleaned switch " that is arranged at operating portion 500 (moment t3), before 405 execution of control part, clean (moment t3～t4).More specifically, control part 405 is by controlling flow switch valve 471 and flow channel switching valve 472, thereby from all multiple guttation mouths 474 water that spues, cleans those guttation mouths 474.Now, control part 405 is not also switched on to electrolyzer unit 450, does not generate sterilized water.Therefore water that, multiple guttation mouths 474 self spue by guttation mouth 474 (comprising the water of being cleaned the inwall reflection of chamber 478 by nozzle) and being cleaned by physics.In addition, the front clean time of implementation was for example about about 2～7 seconds.
Next, control part 405 is by controlling flow switch valve 471 and flow channel switching valve 472, thereby on one side from being arranged on water-discharge portion 479 injection waters of the clean chamber 478 of nozzle, one side is stretched out nozzle 473 in basin 801.Therefore, the housing of nozzle 473 is cleaned (moment t4～t5) by the water spraying from water-discharge portion 479.Now, control part 405 is not also switched on to electrolyzer unit 450, does not generate sterilized water.Therefore, the housing of nozzle 473 is cleaned by physics by the water spraying from water-discharge portion 479.In addition, the clean time of implementation of housing was for example about about 2 seconds.
Next, control part 405 passes through to control flow switch valve 471 and flow channel switching valve 472, thereby from guttation mouth 474 injection waters for " buttocks is cleaned ", cleans " buttocks " (the moment t5～t6) that is sitting in the user on toilet seat 200.Now, control part 405 is not switched on to electrolyzer unit 450, does not generate sterilized water.Therefore, sterilized water can be to user's localized ejection.
Next, in the time that user presses not shown " shutdown switch " by operating portion 500 (moment t6), 405 of control parts pass through to control flow switch valve 471 and flow channel switching valve 472, thereby clean water-discharge portion 479 injection waters of chamber 478 on one side from being arranged on nozzle, on one side nozzle 473 is accommodated in shell 400 (moment t6～t7).It is identical with the clean action of housing of moment t4～t5 that housing is now cleaned action.
Next, be accommodated under the state in shell 400 at nozzle 473, control part 405 is by controlling flow switch valve 471 and flow channel switching valve 472, thereby from all multiple guttation mouths 474 water that spues, those guttation mouths 474 carried out to afterwash (moment t7～t8).The action of afterwash is identical with the front clean action of moment t3～t4, water that multiple guttation mouths 474 self spue by guttation mouth 474 (comprising the water of being cleaned the inwall reflection of chamber 478 by nozzle) and being cleaned by physics.
So, the hygienic washing device 100 that present embodiment relates to, can utilize the water being supplied to physically carry out nozzle 473 housing clean and afterwash, carry out physics clean operation (moment t6～t8).The water yield while carrying out the clean operation of this physics is for example about 450cc/ minute.Thus, can rinse and remove the sewage, the dirt that are attached on nozzle 473.Now, by the water that is used as with warm water utilizing when physics is cleaned operation, the easily sur-face peeling from nozzle 473 by dirts many lubricant component.
Next, control part 405 is switched on to electrolyzer unit 450, generates sterilized water.And control part 405 is by controlling flow switch valve 471 and flow channel switching valve 472, thereby from all multiple guttation mouths 474 sterilized water that spues, those guttation mouths 474 are carried out to afterwash (moment t9～t10).Now, due to the sterilized water that spues from guttation mouth 474, so the sterilized water that multiple guttation mouth 474 self spues by guttation mouth 474 (comprising the sterilized water of being cleaned the inwall reflection of chamber 478 by nozzle) and by sterilization.In addition, the time of implementation of afterwash was for example about about 3 seconds.
Next, control part 405 is by controlling flow switch valve 471 and flow channel switching valve 472, thereby sterilized water is sprayed from the water-discharge portion 479 that is arranged on the clean chamber 478 of nozzle in one side, nozzle 473 is stretched out in basin 801 on one side.Therefore, the housing of nozzle 473 by the sterilized water spraying from water-discharge portion 479 by sterilization (moment t10～t11).That is to say, because control part 405 is switched on and generated sterilized water to electrolyzer unit 450, so the housing of nozzle 473 by the sterilized water spraying from water-discharge portion 479 by sterilization.In addition, the clean time of implementation of this housing was for example about about 2 seconds.
So, the hygienic washing device 100 that present embodiment relates to, sterilization process (moment t9～t11) is cleaned, carried out to afterwash and the housing that can utilize the sterilized water generating in electrolyzer unit 450 to carry out nozzle 473.The water yield while carrying out this sterilization process is for example about 280cc/ minute.That is to say, the water yield of supplying with while carrying out sterilization process (moment t9～t11) is less than carries out the water yield of supplying with when physics is cleaned operation (moment t6～t8).Therefore, can more improve the hypochlorous concentration of the sterilized water generating in electrolyzer unit 450.Even in this case, the water yield that the hygienic washing device 100 relating to due to present embodiment can be many by the water yield than in sterilization process is carried out physics and is cleaned operation, so, clean in operation and occur that the possibility of underfed is also less at physics.
,, in the time carrying out sterilization process, by making sterilized water spread all over widely the outer surface (housing) of nozzle 473, can carry out sterilization to the outer surface of this nozzle 473.In other words,, in the time carrying out sterilization process, do not need the stronger flow of water.This is because the sterilization process of present embodiment not carries out sterilization by the physical action of the flow of water etc., but carries out sterilization by the sterilization component of hypochlorous acid etc.
On the other hand, in the time carrying out the clean operation of physics, need the stronger flow of water.This is to be to be rinsed and removed the sewage, the dirt that are attached on nozzle 473 by the physical action of the flow of water etc. because the physics of present embodiment is cleaned operation.So the hygienic washing device 100 that present embodiment relates to, can be in the case of carrying out sterilization process in the situation that and carrying out physics and clean and make to result from the condition (in the action about Fig. 6 be supplied with the water yield) of hypochlorous concentration different operation.Thus, the hygienic washing device 100 that present embodiment relates to can efficiency carry out sterilization to nozzle 473 well.And, by more improving the hypochlorous concentration generating in electrolyzer unit 450, can allow the clean feel that user produces nozzle 473 improve.
Next, control part 405 carries out " draining " (moment t11～t12).The time of implementation of being somebody's turn to do " draining " was for example about about 60 seconds.Next, control part 405 passes through the action of Control Nozzle motor 476, thereby nozzle 473 is accommodated in shell 400.Time for this nozzle storage was for example about about 2 seconds.
And, in the action of the hygienic washing device 100 shown in Fig. 6, although clean (moment t8～t9) life period interval between operation (moment t6～t8) and sterilization process (moment t9～t11) at physics, also can even without this time interval., physics is cleaned operation and sterilization process both can carry out continuously, also can carry out every certain interval.That is to say, in present specification, clean in the form that operation and sterilization process carry out as a series of action at physics, life period interval between the clean operation of physics and sterilization process and the action carried out is included in the scope of continuous action.
And although will be specifically described in following action specification, this certain interval is preferably physics from buttocks is cleaned and cleans after operation to user and leave the interval till about tens of seconds after toilet seat (induction of taking a seat is closed).If the too empty standard width of a room in an old-style house every, remain in surperficial bacterium and can breed, if do not extend sterilizing time, likely cannot sterilization.
Fig. 7 is the time diagram that illustrates the concrete example of the action of the hygienic washing device that relates to of present embodiment.
First, in the time that seat formula inductive pick-up 404 senses the user who is sitting on toilet seat 200 (moment t1), control part 405 switches to flow switch valve 471 and flow channel switching valve 472 " SC(from clean) " from " initial point ", can be from all guttation mouth 474 guttations for " buttocks is cleaned " and " lower part of the body is cleaned ".Flow (water yield) now is for example about 450cc/ minute.
Next,, in the time completing the switching of flow switch valve 471 and flow channel switching valve 472 (moment t2), 405 of control parts are opened electromagnetic valve 431, and warm water heater 441 is set as to " discharging mode ".Thus, discharge the cold water in stream 20, and carry out warm water preparation.Then, control part 405 is set warm water heater 441 to change to " sterilization control model " afterwards, shut electromagnetic valve 431(moment t3～t4 from " discharging mode ").Even if this is because warm water heater 441 is set to " pass " and also can produces afterwards waste heat.That is, at control part 405, warm water heater 441 being set and changed shut electromagnetic valve 431 afterwards, is for so-called " boiling after preventing ".
Next, in the time that user presses not shown " buttocks is cleaned switch " that is arranged at operating portion 500 (moment t5), 405 of control parts switch to " SC " by flow switch valve 471 and flow channel switching valve 472 from " initial point ", open electromagnetic valve 431, warm water heater 441 is set as " front clean pattern, formally clean pattern, afterwash pattern ".Thus, carrying out the front of nozzle 473 cleans.The temperature of warm water heater 441 now, the design temperature of the warm water heater 441 when " front clean pattern, formally clean pattern, afterwash pattern " is different from the design temperature of the warm water heater 441 in sterilization process described later.To this, will be elaborated in the back.Next, control part 405 switches to flow switch valve 471 and flow channel switching valve 472 " shunt 2 " from " SC ", can clean from being arranged on nozzle water-discharge portion 479 injection waters (moment t6) of chamber 478.
Next, control part 405 makes to be accommodated in nozzle 473 in shell 400 and extend out to the position (moment t7～t8) of " buttocks is cleaned ".Now, due to the opened electromagnetic valve 431 of control part 405, so the housing of nozzle 473 is cleaned by the water spraying from water-discharge portion 479.And, wish to clean as early as possible the requirement of " buttocks " in order to meet user, now the translational speed of nozzle 473 (stretching out speed) is faster than the translational speed in sterilization process described later (advance and retreat speed).
Next, control part 405 switches to " the buttocks flow of water 5 " by flow switch valve 471 and flow channel switching valve 472 from " shunt 2 ", starts formally to clean (buttocks is cleaned) (moment t8～t10).In addition, for example, when user changes to " flow of water 3 " by the flow of water of " buttocks is cleaned " from " flow of water 5 " setting by operating portion 500, control part 405 switches to " the buttocks flow of water 3 " (moment t10～t11) by flow switch valve 471 and flow channel switching valve 472 from " the buttocks flow of water 5 ".Then, control part 405 proceeds formally to clean (moment t11～t12) under " flow of water 3 ".
In the action of above moment t1～t12, control part 405 is not switched on to electrolyzer unit 450, does not generate sterilized water.Therefore,, in the time of " front cleaning " (moment t5～t6) and housing clean (moment t7～t8), nozzle 473 is cleaned by physics by water.And, in the time of " buttocks clean " (moment t8～t12), be sitting in the water that the user on toilet seat 200 " buttocks " spray by the guttation mouth 474 from nozzle 473 and cleaned.
When user presses not shown " shutdown switch " by operating portion 500, control part 405 switches to flow switch valve 471 and flow channel switching valve 472 " shunt 2 " from " the buttocks flow of water 3 ", can clean from being arranged at nozzle water-discharge portion 479 injection waters (moment t12) of chamber 478.Next, the nozzle 473 that extend out to " buttocks is cleaned " position is accommodated in (moment t13～t14) in shell 400 by control part 405.Now, due to the opened electromagnetic valve 431 of control part 405, do not switch on to electrolyzer unit 450, so the housing of nozzle 473 is cleaned by physics by the water spraying from water-discharge portion 479.And in order to prevent that (in retreating) adheres to dirt in the process of storage nozzle 473, now the translational speed of nozzle 473 (astern speed) is faster than the translational speed in sterilization process described later (advance and retreat speed).
Next, be accommodated under the state in shell 400 at nozzle 473, control part 405 switches to " SC " by flow switch valve 471 and flow channel switching valve 472 from " along separate routes 2 ", by from carrying out afterwash (moment t14～t15) for all guttation mouth 474 guttations of " buttocks is cleaned " and " lower part of the body is cleaned ".Due to now also opened electromagnetic valve 431 of control part 405, do not switch on to electrolyzer unit 450, so the part of the guttation mouth 474 of nozzle 473 is cleaned by physics by water.
So, the hygienic washing device 100 that present embodiment relates to, can utilize the water being supplied to physically carry out nozzle 473 housing clean and afterwash, carry out physics clean operation (moment t12～t15).The water yield while carrying out the clean operation of this physics is for example about 450cc/ minute.Thus, can rinse and remove the sewage, the dirt that are attached on nozzle 473.
Next, control part 405 shut electromagnetic valves 431, switch to " initial point " (moment t16) by flow switch valve 471 and flow channel switching valve 472 from " SC ".Next, suitably carry out " buttocks is dry " user and leave after toilet seat 200, when through the stipulated time (in this case 60 seconds), 405 of control parts switch to " SC2 " by flow switch valve 471 and flow channel switching valve 472 from " initial point ", with can be from all guttation mouth 474 guttations (moment t17) for " buttocks clean " and " lower part of the body is cleaned ".In addition, control part 405 is opened electromagnetic valve 431, warm water heater 441 is set as to " sterilization control model " (moment t17).And control part 405 starts to switch on to electrolyzer unit 450, start to generate sterilized water (moment t18).Thus, utilize the sterilized water generating in electrolyzer unit 450 to carry out the afterwash of nozzle 473.
Flow (water yield) now is for example about 280cc/ minute.That is to say the flow (for example about 450cc/ minute) when flow is now less than the clean operation of physics.Therefore, can more improve the hypochlorous concentration of the sterilized water generating in electrolyzer unit 450.And control part 405 is set as warm water heater 441 " sterilization control model " (moment t17).Now the temperature of warm water heater 441, design temperature and the physics of the warm water heater 441 under " sterilization control model " are cleaned the design temperature of the warm water heater 441 in operation, the design temperature of the warm water heater 441 under " front clean pattern, formally clean pattern, afterwash pattern " is different.
When the design temperature of the warm water heater 441 under " sterilization control model " is cleaned the design temperature of the warm water heater 441 in operation higher than physics, can more improve the hypochlorous concentration of the sterilized water generating in electrolyzer unit 450.Therefore, now can improve the sterilizing ability of sterilized water, can efficiency carry out sterilization to nozzle 473 well.
On the other hand, when the design temperature of the warm water heater 441 under " sterilization control model " is cleaned the design temperature of the warm water heater 441 in operation lower than physics, can suppress to be attached to sterilized water evaporation or the volatilization on nozzle 473 surfaces.Therefore, now can make the bactericidal action of sterilized water continue longlyer.
And, compared with situation higher than design temperature, can suppress the value of electric current mobile between positive plate 451 and minus plate 452.Therefore, can be suppressed at the Surface Creation incrustation scale of positive plate 451 and minus plate 452, the life-span that can improve electrolyzer unit 450.Particularly, stop switching on to warm water heater 441, or the energising amount of reduction warm water heater 441 is carried out electrolysis.
Next, control part 405 switches to flow switch valve 471 and flow channel switching valve 472 " shunt 3 " from " SC2 ", spray sterilized water (moment t19) with the water-discharge portion 479 that can clean from being arranged at nozzle chamber 478.Next, control part 405 makes to be accommodated in nozzle 473 in shell 400 and extend out to the position (moment t20～t21) of " maximum is stretched out ".Now, due to the opened electromagnetic valve 431 of control part 405, switch on to electrolyzer unit 450, so, the housing of nozzle 473 by the sterilized water spraying from water-discharge portion 479 by sterilization.Next, the nozzle 473 that extend out to " maximum is stretched out " position is accommodated in (moment t21～t22) in shell 400 by control part 405.Due to also opened electromagnetic valve 431 of control part 405 now, switch on to electrolyzer unit 450, so, the housing of nozzle 473 by the sterilized water spraying from water-discharge portion 479 by sterilization.
At this, while utilizing the sterilized water spraying from water-discharge portion 479 to carry out sterilization to the housing of nozzle 473, the translational speed (advance and retreat speed) of the nozzle 473 of (moment t20～t22) is slower than the translational speed (astern speed) of the nozzle 473 the clean operation of physics.Thus, the housing of nozzle 473 by efficiency better, sterilization fully.In addition, in the situation that nozzle 473 is telescopic multi-section type nozzle, bacterium is easily in the seam portion breeding each other of adjacent cylinder body portion.Therefore, the translational speed (advance and retreat speed) of the nozzle 473 of control part 405 when making the housing of nozzle 473 carry out sterilization is slower, can efficiency better, fully adjacent cylinder body portion seam portion is each other carried out to sterilization.
Next, be accommodated under the state in shell 400 at nozzle 473, control part 405 switches to " SC2 " by flow switch valve 471 and flow channel switching valve 472 from " shunt 3 ", by carrying out afterwash (moment t22～t23) from the sterilized water that spues for all guttation mouths 474 of " buttocks is cleaned " and " lower part of the body is cleaned ".Due to also opened electromagnetic valve 431 of control part 405 now, switch on to electrolyzer unit 450, so the part of the guttation mouth 474 of nozzle 473 is by sterilized water and by sterilization.
So, the hygienic washing device 100 that present embodiment relates to, sterilization process (moment t17～t23) is cleaned, carried out to afterwash and the housing that can utilize the sterilized water generating in electrolyzer unit 450 to carry out nozzle 473.As previously mentioned, the flow while carrying out this sterilization process is for example about 280cc/ minute.That is to say, the water yield of supplying with while carrying out sterilization process (moment t17～t23) is less than carries out the water yield of supplying with when physics is cleaned operation (moment t12～t15).
, control part 405 can be carried out local clean or the setting flow of flow when physics cleans operation is carried out sterilization process to be independent of.More specifically, for example, control part 405 can detect according to the voltage applying in electrolyzer unit 450 water quality (such as electrical conductivity etc.) of tap water, and controls flow by the concentration of the chlorion in prediction tap water.Or for example, control part 405 can be predicted according to the indoor room temperature in washroom the reproduction speed of bacterium, and calculates required hypochlorous concentration according to this reproduction speed, thereby control flow.
In addition, control part 405 can be carried out local clean or the design temperature of warm water temperature when physics cleans operation is carried out sterilization process to be independent of.More specifically, for example, control part 405 can detect according to the voltage applying in electrolyzer unit 450 water quality (such as electrical conductivity etc.) of tap water, and controls warm water temperature by the concentration of the chlorion in prediction tap water.Or for example, control part 405 can be predicted according to the indoor room temperature in washroom the reproduction speed of bacterium, and calculates required hypochlorous concentration according to this reproduction speed, thereby control warm water temperature.
And, as previously mentioned, can, according to the design temperature of the warm water heater 441 under " sterilization control model ", obtain respectively efficiency and the continuation of sterilization.Therefore, for example, control part 405 is in the time of the sterilization process (afterwash) of moment t17～t19 and the sterilization process of moment t19～t21 (housing is cleaned), warm water heater 441 can be set in to temperature high while cleaning operation than physics, on the other hand, in the time of the sterilization process (housing is cleaned) of moment t21～t22 and the sterilization process (afterwash) of moment t22～t23, warm water heater 441 can be set in to temperature low while cleaning operation than physics.Thus, before nozzle 473 stretches out from shell 400 or while stretching out, can utilize the sterilized water that hypochlorous acid concentration improved more and efficiency is carried out sterilization to nozzle 473 well, on the other hand, in the time that nozzle 473 is accommodated in shell 400 or after storage, can make the bactericidal action of the sterilized water that is attached to nozzle 473 surfaces continue longlyer.
And, in this concrete example, although hygienic washing device 100 is to carry out physics to clean operation before user leaves toilet seat 200, and carries out sterilization process after user leaves toilet seat 200, be not limited to this.For example, can be also hygienic washing device 100 after user leaves toilet seat 200, as a series of action, carry out physics and clean operation and sterilization process.Or, for example, can be also hygienic washing device 100 in the time carrying out warm water warming-up exercise (moment t1～t4), as a series of action, carry out physics and clean operation and sterilization process.Even in this case, also, due in the time that the front clean and housing of moment t5～t8 is cleaned, the sterilized water in stream 20 is replaced by the water of new supply, so sterilized water can not be ejected into user's part.But when user is sitting on toilet seat 200, dirt is likely attached on nozzle 473 if consider, being more preferably the housing that nozzle 473 is advanced and retreat clean is to carry out after user leaves toilet seat 200.And as shown in the aforementioned content about Fig. 6, in this concrete example, the action that physics is cleaned operation and sterilization process can be also to carry out continuously.
As discussed above, according to present embodiment, can carry out and utilize sterilized water to carry out the sterilization process of sterilization to nozzle 473 and utilize water to carry out clean physics to nozzle 473 and clean operation.And hygienic washing device 100 can be in the case of carrying out sterilization process in the situation that and carrying out physics and clean and make to result from the condition of hypochlorous concentration different operation.Thus, can efficiency carry out sterilization to nozzle 473 better.And, can allow thus the clean feel that user produces nozzle 473 improve.
And, in above-mentioned concrete example, clean in operation and sterilization process at physics, in order to make to result from the condition difference of hypochlorous concentration, although be temperature, the flow that has regulated water, can also be in addition by regulating current value to regulate concentration.And, as sterilized water supply part, as the example of situation that utilizes electrolytic cell, can be also the mode that adopts wash-out silver.Or, can be also to adopt to make bactericide such method soluble in water bit by bit, can be also to utilize water to be heated to be steam or the hot water after high temperature.In addition, in sterilization process, can be also in the time that nozzle 473 is incorporated in the clean chamber 478 of nozzle, from housing section is carried out clean water-discharge portion 479, sterilized water being sprayed with vaporific, thereby carry out sterilization together with the inwall of the clean chamber 478 of nozzle.
Above, embodiments of the present invention are illustrated.But the present invention is not limited to these and describes content.As long as possess feature of the present invention, those skilled in the art to above-mentioned embodiment suitably in addition the technology after design alteration be also contained in scope of the present invention.For example, what the shape of each critical piece that hygienic washing device 100 grades possess, size, material, configuration etc. and nozzle 473, nozzle were cleaned chamber 478 arranges form etc., is all not limited to illustrated content, can suitably change.
In addition, as long as technical feasible, each critical piece that the respective embodiments described above possess can combine, as long as comprise feature of the present invention, has combined the technology of these contents equally within the scope of the present invention.
